Note 1: Typical parameters are defined as the 60% yield of parameter distributions of individual amplifiers, i.e., out of 100 LT2179s (or 100 LT2178s) typically 240 op amps (or 120) will be better than the indicated specification. Note 2: This parameter is tested on a sample basis only. All noise parameters are tested with VS = ±2.5V, VO = 0V. Note 3: This parameter is guaranteed by design and is not tested. Note 4: Power supply rejection ratio is measured at the minimum supply voltage. The op amps actually work at 1.7V supply but with a typical offset skew of –300 µV. Note 5: This parameter is not 100% tested. Note 6: During testing at –40 °C, the 5V power supply turn-on time is less than 0.5s. Note 7: The LT2178C/LT2179C are designed, characterized and expected to meet the industrial temperature limits, but are not tested at – 40 °C and 85 °C. I-grade parts are guaranteed.
